Bring an umbrella, rain in the forecast

A slow-moving cold front early this week and then a upper-level disturbance a few days later are likely to spark showers and thunderstorms, according to the National Weather Service. Forecasters said the first system will likely dump rain north of the metropolitan area, but the second system has a better chance of bringing rain to the region. The heaviest rain from the second storm could be in coastal communities, forecasters added.

On Tuesday, a 20 percent chance of scattered showers is possible during the day, increasing to about 50 percent at night as the mild cold front passes through the area. Forecasters said a chance for isolated severe thunderstorms, especially in the afternoon and evening, is possible southwest of a line from Angleton to Richmond and Bellville. A severe thunderstorm watch is in effect until 7 p.m. for Matagorda and Jackson counties. Some storms could pack high winds and hail.

The high will be near 86 degrees under mostly cloudy skies. The low will be about 70.

Rain chances drop to about 30 percent Wednesday and about 20 percent that night. The high will be near 81 degrees under partly sunny skies. The low will be about 64. North winds will be between about 5 mph to 10 mph and will probably become easterly at about 5 mph during the night .

The area dries out briefly during the day on Thursday. The high will be near 83 degrees under partly sunny skies. The low will be about 66. A 50 percent chance of rain is possible late at night as the upper-level disturbance moves toward the region.

Rain chances continue Friday, when a 50 percent chance of showers and thunderstorms is possible. The high will be near 80 degrees under mostly cloudy skies. The low will be about 65.

Rain chances drop to about 30 percent Saturday as the front moves away from the area. The high will be about 83. The low will be near 64.

Sunday is likely to be dry and warm. The high will be in the lower 80s while the low will be in the lower 60s. No rain is forecast.
